java - Hibernate transaction begin and commit at the right point -

i have dao package daoclasses implements amongst others following methode:

public class xdaoimpl implements xdao {      private sessionfactory sessionfactory;      public void setsessionfactory(sessionfactory sessionfactory) {         this.sessionfactory = sessionfactory;     }      public sessionfactory getsessionfactory() {         return sessionfactory;     }      @override     public void saveorupdate(myobject o) {             //transaction trans = getsessionfactory().getcurrentsession().begintransaction();             getsessionfactory().getcurrentsession().saveorupdate(o);              //trans.commit();         } } 

if run application needs lot time store objects database. belief happens because create new transaction each object. tried use spring framework’s xml based declarative transaction implementation. till not work me:

the error thrown:

it looks don't have aop jar files in class path.
